GRPC on web service

Hi, I created a web service for my GPRC API app to expose it to the internet, but I am getting this error:

Error starting gRPC call, HttpRequestException: Operation timed out (https://myapp.onrender.com:10000) SocketException: Operation timed out

I am able to connect from another app inside my Render account using the internal address, but not from an external app which is not hosted in Render.

Any idea? Thank you in advance. :pray:

Have you tried using https://myapp.onrender.com from outside - notice no port in the URL on external connections.

@John_B Thank you for the reply

I have tried it, but it returned me these
